What has been disclosed are the means and method for erecting a structure of preformed, interlocking structural elements which may be assembled by unskilled workmen. The preformed structural elements are provided in selected color and texture and include insulative coating surfaces. The interlocking mating configurations of the preformed elements assure a structure whose elements are assembled plumb and true by virtue of their longitudinal axes intersecting orthogonally. The erection of offices, storage, and housing facilities is envisioned utilizing such preformed structural elements. The low cost of materials and the ability to erect structures utilizing the efforts of local, unskilled labor responds to existing immediate needs for housing and other building facilities.
